The Medicinal Herb Info site was created to help educate visitors about the often forgotten wisdom of the old ways of treating illnesses. Many of today's drugs and medicines were originally derived from natural ingredients, combinations of plants and other items found in nature.

We are not suggesting that you ignore the help of trained medical professionals, simply that you have additional options available for treating illnesses. Often the most effective treatment involves a responsible blend of both modern and traditional treatments.

We wish you peace and health!

Legends, Myths and Stories

Herbs were well known in ancient Egypt. And in the Bible, Exodus 12:22, “And Ye shall take a bunch of hyssop, and dip it in the blood that is in the basin, and strike the lintel and the two side posts with the blood that is in the basin; and none of you shall go out of the door of his house until the morning.” Scholars believe the hyssop of this reference is Origanum aegyptiacum rather than Hyssopus officinalis.

David, of the Bible, knew the benefits of hyssop. He drew lessons from the remedy, which he used in showing the cleansing of the body from sin, for he said, “Purge me with hyssop, and I shall be clean; wash me, and I shall be whiter than snow” (Psalms 51:7).

Planted as a companion to cabbage (deters the cabbage moth) and grapes. Keep away from radishes.

Hyssop is an herby fragrance used in Chartreuse, Benedictine and other liqueurs.

Hyssop is historically known as a holy herb, used for cleansing sacred places. Hyssop is a name of Greek origin, adopted from the Greek azob (a holy herb), because it was often used to clean the temples and other sacred places.

Hyssop is used in essentially the same way as sage, with which it is sometimes combined to make a gargle for sore throats. Hyssop tea can be used for poor digestion, breast and lung problems, expels worms, gravel in gall bladder, conjuncivitis, fever sores (fever blisters), chew dried leaves for toothache, used with horehound for bronchitis and asthma, coughs due to colds, nose and throat infections, consumption, mucous congestion in the intestines, laxative, cystitis, flatulence, scrofula, dropsy, and jaundice.

Harvesting takes place when the first flowers are about to open. The oils and flavor off all herbs are in the leaves and green stems and not in the wooden parts. Drying usually completed in 2 days.

Hyssop tea is made by pouring a pint of boiling water over an ounce of the green tops and is considered excellent tasting.

Infusion: steep 1 tsp. dried herbs in 1/2 cup water. Take 1/2 to 1 1/2 cups per day, a mouthful at a time. For breast and lung problems, sweeten with honey if desired.

Prepare a standard infusion of the leaves and diced stem. As a lotion, this brew relieves inflammation and bruising, being noteworthy for its beneficial effect on black eyes.

Decoction: use 1 tsp. herb with 1 cup water. Take 1 to 2 cups per day.
